. vention are capable of use as a tumbling barrel.

It is the object of the present invention to provide a. concrete mixer of very simple con-- struct ion wherein the introduction of the ma- .terial and the mixing of the materials and also the dumping of the-mixed materials is greatly facilitated. \Vhen the barrel is used for the reception of concrete then it is mounted on a suitable truck for transportation from place to place and on the truck is also mounted a power unit preferably in the form of a gasolene engine. ,When the structure is used as a tumbling barrel then it may be mounted upon stationary supports and unay be operated from any convenient source of. power.

The invention will be best understood from a consideration of the following detail description taken in connection with the accompanying drawings forming a part of this specification, in which drawings,

Figure 1 is an elevation of the concrete mixer with one position of the parts shown in solid lines. and other positions of the parts shown in dotted lines. Fig. 2 is a plan view of the structure shown in Fig. 1 with some parts omitted and others shown in section. Fig. 3 is an elevation of a tumbling barrel conforming in part to the structure shown in Figs. 1 and 2. Fig. 4 is a cross section of the barrel taken immediately above the guide rollers.

Referring to the drawings and more especially to Figs. 1 and 2 there is shown a framework 1 of general rectangular form composed of side beams and end beams, preferably of angle iron or structural steel and between the ends the side members are connected by two spaced cross beams 2+3.

The frame 1 constitutes the upper member of a body supported upon wheels 44 at one end and upon other wheels 5'5 at the other end, the last named wheels being mounted upon an axle 6 carrying a fifth wheel 7 upon which is supported the corre- Patentedlreb. at, 1211.

of engine may be used if desired. The shaft .1

ofthe engine 10 carries a pinion 11 for a purpose which will presently appear.

About midway of the length of the beam 3 there is secured thereto a journal bearing 12 and in this journal bearing there is mounted a short shaft 13 carrying at one end a gear wheel 14 in mesh with the pinion 11 and at the other end a bevel pinion 1 5 to which reference will presently be made. Mounted to turn about the longitudinal axis of the shaft 13, between the bevel pinion 15 andbearing 12, is one end of a .U-shaped yoke 16 which is-provided with a trunnion matching the shaft 13 and journaled in a bearing 17 secured on the beam 2 about midway of its length. The yoke 16 has at approximately the middle portion a journal bearing 18 formed thereon and this bearing receives a pin or'stud l9 projecting axially from a barrel 20 of approximately cylindrical form with frusto-conical ends, the end carrying the pin or stud 19 being closed,a-nd the other end being provided with an opening 21 surrounded by a flange 22. The bar- "rel 20 has formed on its outer surface about midway of its length a circumferential flange 23 having one face formed with bevel gear teeth 24 in mesh with the bevel pinion 15. Carried by the ends of the yoke 16 is an annulus 25 surrounding the barrel 20 on the bevel gear teeth side of the flange 23 and spaced both from the barrel and from the said flange. The annulus 25 carries an annular series of spaced rollers 26in engagement with the outer surface of the barrel 20 close to the annular gear 24 thus serving as an embracing anti-friction bearing for the barrel and relieving the pin 19 from side strain.

I The yoke 16 at the end remote from the shaft 13 carries acrown gear 27 having its web parallel with the beam 2. Mounted on the beam 2 near the ends are short shafts 28 and 29 respectively and these shafts carry at their inner ends bevel gear wheels 30 .in mesh with the crown gear 27. The outer ends of the shafts 28 and 29 extend beyond the yoke 34 extends above the correspond-v ing side of the scoop and is there formedinto a hook 37 to which may be secured a pulley 38 having a rope or cable 39 extending therethrough and to the other side of the machine. v The outer end of the scoop 35 is closed and is supported by a bracket extending from the yoke 34 near the pivot point thereof to the outer end of thescoop or hopper 35.

Let it be assumed that it is desirable to mix a charge of concrete with the machine arranged as shown in Fig. 1 and let it.

also be assumed that the engine 10 is running and therefrom through the pinion l1 and gear 14 rotative movement is imparted to the barrel 20 by way of the pinion 15 and gear-24, this rotary-motion on the pin 19 as an axis continuing during the operations about to be described. Under the conditions assumed the crank 31 is upon the shaft 29 and upon turning the crank in the proper direction the barrel is turned on the axis of the shaft 13 until the mouth or opening 21 is toward the scoop 35 as indicated in dotted lines in Fig. 1 but with the mouth higherthan the end of the barrel carrying the pin 19. In the meantime the proper mixture of cement and sand and gravel is thrown into the scoop or hopper 35 while the latter is held by the rope 39 with its closed end lower than the discharge end. lVater is also thrown into the barrel 20 and then by a proper manipulation of the rope 39 the discharge end of the scoop is moved toward the receiving mouth 21 of the barrel and because of the movement of the scoop about the pivot pin 33 the closed end of the scoop is raised and the discharge end is lowered so that the charge of material within the scoop gravitates therefrom into the barrel .20 through the mouth 21. The rotary motion of the barrel about its longitudinal axis which agrees withthe longitudinal axis of the pin 19 continues because of the continuing running of the engine 10. It may be assumed that suitable mixing blades are introduced into the barrel 20, but these being common expedients it isnot deemed necessary to illustrate them. The barrel may now be rotated about the axis of the yoke 16 by turning the shaft 29 in the reverse direction to its first rotation and the barrel is finally returnedto the position shown in full lines in Fig. 1. By this time the contents of the barrel, into which additional water has been thrown as is needed, have become thoroughly mixed and a continued movement of the shaft 29 in the same direction as justdescribed will lower the discharge mouth 21 of the barrel until it is in the lowermost position shown in dotted lines in Fig. 1 below the solid line position there shown and the contents of the barrel will then gravitate therefrom and may be received into'any suitable receptacle. While the operations just described have been taking place the hopper 35 has been returned to its first position, shown in solid lines in Fig. 1, and more material has been introduced thereinto so that by returning the barrel to the proper position with its mouth toward the hopper it is again ready to receive the contents of the hopper when the closed end of the latter is elevated again to the dotted line position of Fig. 1.

\Vith this apparatus the operation of re ceiving, mixing, dumping the mixture and returning the barrel for a fresh charge is practically continuous and the capacity of the-apparatus is therefore commensurately large.

In Fig.4 the barrel 20 is shown arranged as a tumbling barrel and the barrel with the yoke 16 annulus 25, rollers 26, and gear 24 doesnot differ from the structure described with reference to Figs. 1 and 2. Inplace of the shaft 13 there is provided a" shaft 13 carrying a bevel gear 15 meshing with the gear 24. In place of the beams 2 and 3 and the frame 1 the yoke 16 is mounted on a support comprising two spaced standards 46 and inv place of the crown gear 27 the yoke 16 has secured thereto a gear wheel 47 in mesh with a pinion 48 on a shaft 49 journaled in one of thepstandards 46 and to the outer end of this shaft there is secured a crank 50. Loose on the shaft 13 is a belt pulley 51 and the shaft 13 also carries a clutch member 52 adapted to engage another clutch member 53 on the pulley 51. This clutch may beordinary type and may be operated in any desired manner and so needs no special descriptionflBya suitable manipulation of the crank '50 themouth of the barrel may be brought into position to receive articles-to be tumbled and may then be again returned so that the mouth is uppermost while the barrel may belrotated continuously about the axis of the pin 19 by power applied to the pulley 51, orthe power may be cut off from the barrel at any time by disconnecting the clutch members 52 and 53.

In the concrete mixing structure of Figs. 1 and 2 the charging and discharging of the barrel may take place from either side of the frame 1 by reversing the positions of the crank 31 and the hopper 35.

The device described is advantageous in that it may be set in any position for workllU esaeea ing or for filling and may be dumped or discharged from either side, since the barrel is hung orpivoted near its center, the whole operation being therefore very easy. The hanging of the barrel from the middle brings it at a convenient height for filling and dumping while enabling it to dump into a high receptacle and can also be filled in a comparatively low position. Furthermore, by providing the large bevel gearing encircling the central portion or the waist of the barrel a larger wearing surface is provided than is usually used while the small driving gear for the large bevel gear is located beneath the latter and the overhanging of the bevel gear protects the teeth from lodgment of gravel or dirt therein, thus protecting both gears which is of especial advantage in the concrete mixing.

What is claimed is 1. In an apparatus of the class described, a rotatable barrel, a supporting yoke for the same, the barrel having an axial pin journal engaging a suitable bearing on the yoke, and said yoke having an annulus surrounding the barrel about midway of its length,

rollers carried by the annulus and engaging the outer wall of the barrel, a crown gear on the barreladjacent to the rollers and having its teeth directed downwardly when the barrel is in normal operative position and a driving pinion for the gear located beneath the said gear.

2. In an apparatus of the class described a substantially cylindrical barrel having one end closed and the other end contracted and provided with an opening, said barrel also being provided at the closed end with an axial pin, a yoke provided with a bearing for the, pin on the barrel and also provided with {an annulus surrounding the barrel about midway of its length, rollers-carried by the annulus and engaging the outer wall of the barrel, a crown gear on the barrel adjacent to the rollers and having its teeth directed downwardly in the normal position of the barrel, pivot supports for the yoke on an axis traversing the barrel at right angles to the longitudinal axis of said barrel, a driving gear engaging the bevel gear and located below the same, a gear carried by the yoke, and means for causing the rotation of the last named gear and by it the rotation of the yoke with the barrel on the gitudinal axis adapted to the journal bearing in the yoke, and engaged about its middle portion by the rollers carried by the annulus of the yoke, said barrel also being" provided with an annular crown gear adjacent to the point engaged by the rollers, and
